Wide angle primes is a problem. And the old ones are very very rare.
There is a black 20mm FA, the 31 Limited and a silver SMC Pentax-FA * IF AL 24mm F2For portraits there are, besides may be the 100 and the older SMC Pentax-FA * IF 85mm F1.4, only manuel portrait lenses.The Samyang 135/2 seems to be outstanding and not expensive. The Samyang 85/1.4 does not have very good reviews.
Oh I forgot there is the older Sigma AF 85/1.4

Re: Fun with images taken with the Pentax K1

Thanks both

I think if the sensor is as good as people are saying then it really needs something like a Zeiss 135f2 or Otus or similar with really good optics to make the most of it, I would be using it for work and would much prefer to buy high quality lenses new for it than trawl classifieds for legacy glass, there's a degree of security when it needs to work if I can go back to a dealer. Not worried about wides to be honest, would just like a capable camera for lower light stuff. I will have a read up of whats available in a K mount but it may make more sense just to go with a D810 knowing there is plenty of fine glass already available.

Looking forward to seeing how the 100 performs on portraits, it may do the job.

The 77mm is a current lens, and one of the first I would buy for a K-1:

Re: Fun with images taken with the Pentax K1

Any suggestions for an adapter that would allow me to use my Nikon mount Otus lens on the Pentax K-1? I just ordered a K-1 because I've been blown away by the image quality but I'm new to the Pentax system and could use some guidance.

Not sure of what native Pentax lenses meet the high quality of the Zeiss lenses but I'm looking forward to trying.

Leitax seems to be working on Pentax mounts for the Zeiss in nikon mount lenses, but I don't think/know if the Otus series will be part of it. You can contact him and ask.

Re: Fun with images taken with the Pentax K1

A portrait lens is the main missing item, but Sigma should step up this autumn, although whether for the K mount is unclear.

Re: Fun with images taken with the Pentax K1

That is bad news Quentin! I am seriously thinking about this lens. Can't you correct it? I could not find the tool for it; whatever the name was..

Michiel,

I have been working to fix the issue today and I think I have.

The lens has very little throw. Between 1 meter and infinity it's just a short turn of the focussing ring

The problem is that the phase detection autofocus with the lens focuses far too close, in front of the subject, if not adjusted. The problem is not there with contrast detection, of if you focus manually using live view.

I have dialled in -7 in the fine adjustment and that seems to fix the problem (for my copy of the lens), but better still, use contrast focus with live view.

Good lens if you do!

Good job I spent some time fixing the issue, as I have purchased the Lee Filter 150 system and Lee Tamron sized filter holder (same as the Pentax, unsurprisingly). Thought I'd wasted my money

Yes that's what I mean Fine adjustment, I looked for it for a moment but could not find it. I am glad the possibility is there.
And as Tjanik says, a portrait lens is not the problem with the FA limited 77. I have seen wonderful work with it.
And the 31 is a great lens as well. Together with the 43 limited they call it the holy trinity.
Problem is they don't come cheap. I have to wait a little, need to sell some other lenses first to fund new ones. Don't want to spend more money on photo stuff for a while.
Looking forward to your first (city) outing with the 15-30!

I have been playing with the Voigtländer Ultron 40 aspherical 40/2 SL. I think I like it. It is a A lens and it is really small. Nice walk around lens.
I must say; the focus beeb works faster as focus peaking, but I knew that already from 645Z.
Once again, they are discontinued. Cameraquest seems to be the only place who has a few new ones left.

Re: Fun with images taken with the Pentax K1

Hi Thorkil

Ahh, glad you noticed It's by a pond where light filters through leaves on surrounding shrubs and some light dapples the foreground. I took a number of shots of this candelabra primula just an the afternoon sun caught it. Much as I love pixel shift, it really cannot be used for hand held botanical macro work.

Hi Quentin...okay, without pixelshift, and handheld, I do think it looks even more impressive! well done.

Ps. I guess stabilization then is a great bonus

Thanks, and yes it is useful to have stabilization but its hit and miss whether its truly sharp, and focussed on the right spot. This was one of about 20 attempts... The K1 has excellent natural colour that other cameras don't easily match.

Re: Fun with images taken with the Pentax K1

The K-1 arrived a few days ago. Just starting to get the hang of it. The first thing I noticed that it was not as big as reviewers were saying. Feels quite comfortable in the hand actually. I have lots of glass to try on it over the next few months.

This lens had a little bit more difficulty in locking focus in low light, although I did not notice any vignetting at all (as this lens sits on the edge of being full frame or APS-C). Gotta love the colors though....plus a little bit of 3D.....maybe?
